Process of application and cooling of adhesive for glueing cartridge packages and similar

ABSTRACT

The present object concerns an innovative glueing process for cartridge paper boxes, with an application of adhesive, of the “hot-melt” type, on the lapel of the outer tab, for three-tabbed cartridge boxes, featuring a process of heating and melting over the sites of application of the adhesive, by the use of air-pistols, heated plates and other means, drying naturally at room temperature, receiving a slight compression. The sealing of the package is achieved by the use of a “window” on the main part of the package, with the application of inscriptions by an ink-jet system, or others, over the cartridge and the adhesive, fusing and spreading over the package when heated.

The present object concerns an innovative glueing process for cartridgepaper boxes, with an application of adhesive, of the “hot melt type”, onthe lapel of the outer tab, for three tabbed cartridge boxes, featuringa process of heating and melting over the sites of application of theadhesive, by the use of air-pistols, heated plates and other means,drying naturally at room temperature, receiving a slight compression.

The sealing of the package is achieved by the use of a “window” on themain part of the package, with the application of inscriptions by anink-jet system, or others, over the cartridge and the adhesive, fusingand spreading over the package when heated.

The object as issue is meant to forbid the violation of the cartridgepaper PACKAGES of medicines, avoiding or hindering frauds of thehealth-care system, by the use of a glueing process with hot-meltadhesive.

The current models of cartridges have three tabs, while the presentproposal to seal them is the application of a drop of hot-melt adhesive(hot glue) in their (smaller) inner tabs, with the placement of a outersafety seal. Another is the alteration made to the cartridges with fourtabs, applying a drop or steak of adhesive in the inner tab.

In the first option, the adhesive applied would be set directly in theshaper and sealer of cartridges within the manufacturer's laboratories,with some alterations being made.

In the second option, many changes in the equipment would be necessary.

The process under discussion has the aim of solving these problems, witha quick, suitable and cheap solution, allied to the proper safety, withthe application of hot-melt adhesive in the three-tabled cartridges, inthe lapel of the outer tab the one that closes up the package, goinginto its main part. In the laboratory: all the current process remainsthe same, and after the sealers will be included a system of heating andmelting of the adhesive (which will stick from then on), with thematerial cooling at the room temperature, after a few seconds, by aslight compression.

In this fashion, sealing the cartridge, and as a complement of theprocess, to avoid violations, a “window” may be left, that is, a smallcut in the cartridge to show the glueing. Over this “window”, letteringwould be applied, with safety warnings or ink-jet applications, orthermoplastic adhesives that would be fused if heat was to be applied toopen the cartridge PACKAGES.

BRIEF DESCRIPTION OF THE DRAWINGS

For a perfect understanding and visualisation of the PROCESS OFAPPLICATION AND COOLING OF ADHESIVE FOR GLUEING CARTRIDGE PACKAGES ANDSIMILAR, under discussion, the following illustrative drawings arepresented, where:

FIG. 1—shows a perspective view of a cartridge-paper package with asection of adhesive applied over the lapel of the outer tab.

DETAILED DESCRIPTION OF THE MODEL

According to the drawing, and in all details, the PROCESS OF APPLICATIONAND COOLING OF ADHESIVE FOR GLUEING CARTRIDGE PACKAGES AND SIMILAR,under discussion, is characterised by featuring a glueing process (1),for packages of cartridge paper (2) having an application of adhesive ofthe “hot-melt” type (3) in the lapel of the outer tab (4), forthree-tabbed cartridges (2A), featuring also a process for heating andmelting (5) over the sites of application of the adhesive, by hot-airpistols, heated plates, and other means (5A), being cooled and cemented,afterwards, by a slight compression also granting inviolability of thecartridge by the use of a “window” (6) in the main part of the package(2) with the application of lettering and inscriptions by a ink-jetsystem and others (7) over the cartridge and the adhesive (3), fusingwhen heated, to spread over the package (2).

For the advantages it offers, and for showing truly innovativecharacteristics, the PROCESS OF APPLICATION AND COOLING OF ADHESIVE FORGLUEING CARTRIDGE PACKAGES AND SIMILAR, gathers the necessary conditionsto deserve the Privilege of Patent of Invention.

What is claimed is:
 1. A process for application and cooling of adhesivefor glueing cartridge packages comprising the steps of: applying hotmelt adhesive to a lapel of an outer tab of a three-tabbed cartridgepackage; heating and melting said adhesive via hot air pistols orheating plates; lightly compressing said lapel onto a main part of thecartridge package while said adhesive is naturally cooling andcementing, wherein said adhesive is viewed through a window in a mainpart of the cartridge package after said lapel is adhered to said mainpart of the cartridge package; and applying lettering or inscriptionswith an ink-jet system over the cartridge package and adhesive on saidlapel in a region viewed through said window, wherein said inscriptionsfuse and spread over the cartridge package if heat is applied to openthe cartridge package.
